Replacing my terminal hear exchanger with another used one. Old one rusted through and through. I tried to keep the old one alive by applying heat paint, but was not successful. Tried 1200 degree manifold paint, POR heat paint and others, and was careful about prep before applying paint. Winter salt worked itself under the paint and the resulting rust was worse.
Anyone have success with painting their heat exchanger and if so, what have you used?
Thanks
Michael

In an old post I outlined how I had split the heat exchanger cover/casing so I can easily "clean" inside, when the unit is removed from the vehicle.
When I was modifying the casing I had the parts powder coated (in a satin black) which seems to have withstood both time and corrosion well!

I cleaned and painted my heat exchanger about 18 months ago. It was just surface rust with the original (?) paint coming off. I applied some stuff that is used to paint the chimneys of wood burning stoves etc.
There must be a US equivalent of stuff like this. For the record, the product is "Calfire Stove Bright High Temperature Paint". Says it's heat resistant to 650 degrees C. "For stoves, fireplaces, barbecues, cookers, artificial logs and coals"
It's a very thin, black paint. You have to constantly stir it to keep the goodies in suspension. I gave the exchanger a severe worrying with a wire brush beforehand, then two coats of this stuff. Seems to work OK.
Your local stove dealer may assist. Hope this is of help.

I had the heat exchanger painted with black high-temperature paint (exhaust paint) when the exhaust was last taken off for body work.
Seems to work OK since then. The paint smells a bit the first times you run your truck, but nothing worse to report...
I don't know for how long this will help keeping rust at bay... but it does look better than before

What about some of the high-heat ceramic coatings?
This place can do it for headers;
